My dc are bilingual and have spent half of the last school year abroad to catch up on their minority language. They both loved it and for dd1 in particular the style of teaching worked much better. Unfortunately it wasn't possible for us to relocate permanently, not is it possible to split each school year in half. I'm now thinking yet again about HE because the long school day in the Uk means there is little time in the day/week to pursue a different curriculum set in a different language and culture.
Has anyone done this type of cross cultural HE successfully?
